It’s intuitive to think about squaring or doubling something. It’s just a number multiplied by itself.
In this lesson, students use concrete models to explore square numbers and square roots and confront the philosophical and moral questions posed by the existence of irrational numbers.
This activity is designed to give students the opportunity to explore, visualize, and create a representation of the relative lengths of the square roots from 1-10.
In this grades 9‑12 lesson, students use a computer software program to assist them in determining the square root of 2 to a given number of decimal places.
This activity uses a series of related arithmetic experiences to prompt students to generalize into more abstract ideas.
This lesson prompts students to explore ways of arranging squares to represent equivalences involving square- and cube-roots.
